Where I’m from , MIlwaukee, there’s a major difference in accent just from north side to southside. I’m a southsider and my wife is Northside. People where I live always guess Brooklyn or Canada, because we “eh” a lot. “Eh” can start or end any sentence. That and we don’t pronounce our “th”, and opt for /d/ or /t/ instead. Dat’s why dey tink soutsiders are from Brooklyn.
